Su Bai didn't trust the unknown plants in the primitive society. He had to see everything with his own eyes before he could feel at ease. After all, it was related to the water supply of the tribe.
He said to Flame Horn,"Get me a hollow tree."”
"Alright." Flame Horn didn't say anything and turned around to charge into the forest.
"Chief, I'll go." Another silent totem warrior.
He was called Big Melon and quickly said,"The strongest person should stay here to protect Wu."”
" Uh…" Flame Horn only reacted after hearing this. The most important thing was still shamans.
"Tsk!" Yan Hua glanced at her embarrassed father and could not help but purse her lips. Her father's impulsive personality could not be changed.
Yan Jiao saw his daughter's disdainful gaze and shouted,""Don't be lazy. Hurry up and help dig the pit.”
"Oh ~~" The bull-horned girl let out a dissatisfied sound. Seeing that her father was about to get angry, she quickly ran to dig a hole.
"Humph!" Flame Horn snorted. He turned around and saw Su Bai's half-smile, so he went to dig a hole.
"Honest chieftain." Su Bai complained in his heart.
He looked at the small lake, paying special attention to the stone-armored crocodiles on the shore, thinking about how to kill one to eat. There were many crocodiles raised on Earth, and they were already served on the dining table.
"Crocodile skin is a good thing, not to mention this Stone-Armored Crocodile. The leather armor can be made into natural armor after some processing.”Su Bai muttered to himself.
In short, he had already thought about the Stone-Armored Crocodile in the small lake. He even thought of how to cook it. Braised, barbequed, fried…
"It's a pity that we can only look at it now and not eat it.”Su Bai sighed.
"Shaman, we found water." Blacktooth shouted excitedly.
"Oh, so fast." Su Bai turned around in surprise and saw Blacktooth covered in mud as if he had rolled in mud.
He walked to the edge of the depression and saw that the three of them had dug out a pit that was more than two meters wide and one meter deep.
"Wu, there's already water here. If we continue digging, there'll definitely be more water.”Blacktooth excitedly pointed at a corner of the mud pit. Some water was already seeping out.
"Then dig deeper. We have to build some stones around the mud pit. When the time comes, we have to cover this puddle with branches.”Su Bai immediately gave the order.
The water source had to be hidden to prevent it from being occupied by the beasts and polluting the water source. After all, it was possible to urinate and defecate anywhere.
"Alright." The three of them replied excitedly.
"Shaman, that's amazing. You can dig a hole and get water. You don't have to go to the lake to get water at all.”Blacktooth said softly as he dug a hole. He couldn't help but admire shamans from the bottom of his heart.
"Yes." Flame Flower nodded heavily and stole a glance at Su Bai. He was suddenly glad that he had been persuaded by the shaman to bring him to the water source. Now, the problem of water source had really been solved.
Flame Horn finally understood why the shaman didn't collect water from the cliff. There was a better way to get water here.
The three of them were now convinced by Su Bai from the bottom of their hearts. He had done something they never dared to imagine.
"Kacha kacha…"
The sound of tree branches scraping against each other came from the forest, immediately making them nervous.
"Shaman, step back." Flame Horn immediately flashed in front of Su Bai.
"What kind of beast could it be?" Blacktooth said in a low voice, his figure following closely to the left.
Flame Flower was about to go to the right, but Su Bai pulled her behind them.
"..." A figure crawled out from the bushes, dragging two hollow logs. He stared blankly at Flame Horn, Blacktooth, and the others who were in formation.
"Big Melon, why aren't you saying anything?" Flame Horn glared at him and said unhappily.
" I..." Big Melon was stunned and didn't know how to answer.
If he hadn't seen the shaman, he would have said," Wasn't it always like this in the past?
"What do you mean you? Hurry up and bring the hollow tree over.”Blacktooth shouted awkwardly.
They had been too anxious about the shaman's safety, and the two experienced totem warriors had not been able to tell if it was a ferocious beast, which had led to such a blunder.
"Oh." Big Melon was very observant. He knew that the two of them were angry out of humiliation, so it was better to be obedient, lest they find an excuse to fall a few times when they went back.
He put two hollow logs that were seven to eight meters long in front of Su Bai and stepped aside.
"Is this the Hollow Tree? It's really a little strange." Su Bai squatted down and looked at the cut surface of the hollow wood.
The two hollow pieces of wood in front of him were about the same size as a thigh. Their skin was brown, and there was a hole in the middle of the wood that was as thick as a thumb.
"The hollow tree is really good stuff.”Su Bai said with a smile. He was very satisfied with the hollow tree. It was a natural water pipe, and the 'pipe wall' was very thick.
Yan Hua's red eyes flickered with curiosity as she asked in a clear voice,""Shaman, what is the Hollow Tree used for?”
"Hollow trees are used to transport water." Su Bai said matter-of-factly.
"What? Transport water?" Yan Hua was stunned.
Flame Horn, Blacktooth, and Big Melon were all a little confused. Why couldn't they keep up with Shaman's thoughts?
This was the first time in his life that he had heard that hollow trees could be used to transport water. His ancestors had never taught him that.
"You still don't understand?" Su Bai tilted his head and asked.
"I don't understand." They shook their heads in unison.
"The water in this puddle is full. Is it going to overflow?”
Su Bai pointed at the half-dug puddle and started to explain: "If we bury hollow wood in the pit, will water flow out from the middle of the hollow wood and connect it with many hollow wood until it reaches the tribe?”
" Hiss…" The few of them sucked in a breath of cold air. They were completely stunned by this idea.
"That's right. Why didn't I think of that?”Blacktooth clutched his head in disbelief.
Flame Horn widened his eyes and shouted in realization,""Connecting all the hollow wood together is a great idea.”
For people in primitive society, this idea might be very simple, but no one would think about it, nor did they dare to think about it.
After all, for people who had to fill their stomachs every day, they would never think of using hollow wood to transport water. Everyone would just get water from the nearby lakes and rivers and use wooden barrels.
"My thoughts have been restricted." Su Bai shook his head. He felt it was time to prepare for cultural education.
It was just like how everyone knew that there was oxygen in the air, but no one taught this knowledge. They had no idea what kind of gas people breathed in to survive.
"Thinking of things that others can't think of, is this what a shaman is?”Yan Hua stared at Su Bai's side profile. What happened today impacted her outlook on life which had remained unchanged for nineteen years.
